Hi Rehan, thank you for using our forum, my name is Luis I am part of the Small business Support community. I apologies for the inconvenience you are having with your Router, did you try to use a different browser such as Mozilla, i.e 9.0 in order to resolve this issue? If not, I advise you to try to access to the device from the laptop using other one browser. Now, if the issues continue, could you share with us the error you are receiving? And also it could be a connectivity issues, you could see if you can reach the router.
If I am not wrong, you are trying to configure your load balancing per schedule, following the admin guide this kind of feature is no possible, the only thing that you can do is enable and disable the feature in the moment that you want to use it or not, you are able to find more information in the admin guide here in Setting Up Dual WAN and Multi-WAN Connections section.
I hope you find this answer useful
Greetings,
Luis Arias.
